Bug 7518: regression test double-quote in search operand

Bug 7518: regression test double-quote in search operand

Under certain circumstances, namely where QueryParser is off,
QueryWeightFields is on, and QueryFuzzy and QueryAutoTruncate are
off, a search with a double-quote embedded in it can fail: for
example

    web application

would return results where

    web "application

does not.

This patch adds an automated regression test.

To test:

[1] Apply this patch and run prove -v t/db_dependent/Search.t;
    two tests should fail.
[2] After applying the main patch that fixes the bug, the
    prove -v  t/db_dependent/Search.t should succeed.
